GUI Attach Button Disabled: USB Device Issue

Hey everyone! Today, we're diving into a fascinating issue reported by a user, vadimgrn, regarding the GUI attach button being disabled for certain USB devices, specifically a mouse, while using usbipd-win. This is a super interesting problem that touches on the intricacies of USB device communication and how software interacts with hardware. Let's break down the problem, explore the potential causes, and discuss possible solutions. We'll keep it casual and friendly, so you guys can easily follow along.

Understanding the Problem: The Grayed-Out Attach Button

Our user, vadimgrn, is leveraging the awesome dorssel/usbipd-win project to share USB devices from one Windows laptop (the server) to another (the main PC). This is a fantastic setup for those who want to access peripherals remotely. The primary goal here is to pass the USB mouse and keyboard to the main PC, making for a smoother workflow. Now, here's where things get interesting. The keyboard? No problem! The GUI attach button works perfectly, and the auto-attach option can be set without a hitch. But the mouse? That's where the GUI attach button is disabled, turning gray and refusing to cooperate.

The mystery deepens when we learn that the mouse can be attached manually using the command-line interface (CLI) with the --bus-id flag. This suggests that the underlying USB connection is functional, but the GUI is encountering some hurdle that prevents it from enabling the attach button. Vadimgrn suspects that the mouse might not be reporting its details correctly, or perhaps there's some other communication hiccup. The provided screenshot vividly illustrates the situation, showing the grayed-out attach button in the GUI alongside the successful CLI attachment.

The core of the issue, as vadimgrn aptly puts it, is the desire for an override in the GUI to allow attaching "invalid" devices. This highlights the need for a more flexible approach to USB device attachment, especially when dealing with devices that might not perfectly adhere to standard reporting protocols. We'll delve into why this might be happening and what kind of solutions could be implemented.

Potential Causes: Why is the Attach Button Disabled?

So, why is this happening? Why would the GUI refuse to attach a device that the CLI can handle with ease? Let's brainstorm some potential causes:

• Device Descriptor Issues: The most likely culprit is that the mouse isn't providing all the necessary information in its USB device descriptor. The device descriptor is like a digital ID card for the USB device, containing details such as the vendor ID, product ID, device class, and supported protocols. The GUI likely relies on this descriptor to determine if a device is valid and can be attached. If the descriptor is incomplete, malformed, or missing certain critical fields, the GUI might deem the device
